Central Pleomorphic Adenoma of Mandible Mimicking Ameloblastoma - A Rare Case Report.

Salivary gland neoplasms account for 3% of all head and neck tumours. Pleomorphic adenoma (PA) is the most common salivary gland tumour that mainly occurs in the parotid gland, followed by minor salivary glands of the oral cavity, however, the occurrence of PA inside the jaw bones is exceedingly rare and very few cases have been reported in the literature. Inside jaw bones these lesions tend to imitate large osteolytic lesions encompass a diagnostic challenge. An exhaustive review of the literature revealed only 10 cases of central pleomorphic adenoma. We present a rare case of primary PA that occurred inside the mandible and was provisionally diagnosed as ameloblastoma.

Cognizance, adverse effects and motivation regarding COVID-19 vaccination amongst health care professionals: A cross-sectional study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccines are currently at the forefront of India's fight against the pandemic. They have been shown to prevent the disease or reduce its severity, following 2 doses given at an interval of 6-8 weeks. OBJECTIVES: The present cross-sectional survey was carried out on 1,145 health care practitioners in order to recognize and evaluate the adverse effects of vaccination as well as knowledge, motivation and attitudes with regard to vaccines amongst the respondents after the 1st dose of vaccination. MATERIAL AND METHODS: An anonymous survey was carried out among different age and gender groups in the medical colleges situated in the state of Maharashtra, India. The participants' responses were collected with the use of the Google Forms platform through sending a URL link to the questionnaire. The validity of the questionnaire was pilot-tested and the obtained Cronbach's alpha value was 0.80. Amongst the 1,145 participants, 92.2% of the respondents received COVISHIELD™ and 7.8% received COVAXIN®. The subjects were further scrutinized in 4 different age groups:18-27 years (73.0%); 28-37 years (14.8%); 38-47 years (9.6%); and above 47 years (2.5%). RESULTS: Adverse effects were common in the age group of 18-27 years and were observed significantly more frequently in females than males. A very common symptom was pain at the site of injection with an occurrence of 85.2%. Fever was present in 62.6% of the respondents, with 39.1% having low-grade fever and very few having high-grade fever. CONCLUSIONS: Knowledge about adverse effects and what to expect after vaccination would help to educate people, dispel misinformation and reduce vaccination hesitancy. It can also help to promote awareness about the incidence of adverse effects and the safety of COVID-19 vaccines.

Aesthetic root coverage with acellular dermal matrix allograft: a shield for gingival recession.

Awareness about root coverage is increasing in day-to-day clinical practice. Patients are more motivated and concerned about aesthetics nowadays along with the issues of sensitivity of teeth. The conventional flap designs and techniques including lateral sliding flaps, coronally advanced flap, subepithelial connective tissue grafts and free gingival grafts are being adopted for root coverage. The newer material including resorbable and non-resorbable guided tissue regenerative membranes, amniotic membrane, platelet-rich fibrin membrane, enamel matrix derivative protein, xenogenic collagen matrix graft along with the soft tissue substitute like acellular dermal matrix allograft are also being used for recession coverage. The present case report describes a case of 22-year-old female patient with the chief complaint of denudation of gums exposing the root surface over the mandibular left central incisor. The soft tissue substitute acellular dermal matrix allograft was used for root coverage as the patient was not willing to procure an autogenous palatal graft. The results were satisfactory with complete root coverage.

Novel technique for esthetic root coverage with titanium prepared platelet-rich fibrin.

Leukocyte- and platelet-rich fibrin (L-PRF) can be defined as an autologous leukocyte and platelet-rich biomaterial. Unlike other platelet-rich products, this technique does not require an anticoagulant or bovine thrombin. However, it is simply centrifuged blood without any additives, which makes it possible to avoid all of the legal restrictions related to the reimplantation of blood-derived products. L-PRF is composed of a fibrin matrix polymerized in a tetramolecular structure and is involved in the joining of platelets, leukocytes, cytokines, and circulating stem cells. The use of silica- coated test tubes is arising a lot of queries about the safety of L-PRF prepared within these test tubes. So, to avoid the use of silicacoated test tubes, titanium prepared PRF has come in practice now, as titanium is biocompatible metal and has property of histoconduction. The present case report is about successful esthetic root coverage around mandibular anterior teeth with clinical attachment loss of 4-5 mm at baseline. The patient had reduced sensitivity, CAL was 1 mm, and attached gingiva covered denuded root surface after 15 days and after 3-month recall appointment.
